The converter changes can be found in sections 3.7, 10.5, and
11.1.10-11.

The following open issues are pending:

* Conversion of @Id and @Version.

* Explicit listing of converters in persistence.xml file. I'm not
sure I understand what
was being proposed here.

When the archive is not scanned (it's an option in persistence.xml),
the provider has no way of finding the list of converters unless the
user explicitly list them in persistence.xml like it does list classes.

OK, thanks -- so would you propose that they simply be listed using
the class element?

These are O/R mapping classes. Why would they be listed in
persistence.xml? The flag to not scan for annotations (the
xml-mapping-metadata-complete option) is in the orm.xml mapping file,
that is where I would expect to specify these when not using
annotations, right?
